Bookbinding Unit - Bookbinding unit eliminating the necessity of a user, in placing collated inner leaves onto a tray, pre-measuring the bundle thickness, and the danger of fingers getting pinched during the placement. Furnished with: inner-leaf tray; coversheet tray; gripping conveyor gripping and transporting bundles of leaf-tray sheets; coversheet conveyor feeding coversheet-tray covers and placing them in a binding location; adhesive applicator applying adhesive to bundle spine-portion endfaces; cover binder binding bundles and covers together; and controller encasing bundles in covers to form booklets. A first detector, in the inner-leaf tray, detects thickness of bundles therein, and a second detector, in the gripping conveyor, detects thickness of the gripped bundles. The controller prohibits the gripping conveyor from conveying inner leaves out from the inner-leaf tray when the thickness of a sheet bundle detected by the first detector is more than a predetermined thickness.
